Water quality can also be address along Copper Creek itself. Currently an engineering firm has been retained to study the hydraulics of this site to improve water quality. It is anticipated a small wetland could be incorporated into this site that would filter water from Copper Creek before it enters Fourmile creek immediately southwest of the site.
